Description

  The present invention relates to the field of subdivided beverages that use capsules to prepare a beverage in a beverage brewing apparatus. The invention particularly relates to improved capsules and methods for preparing beverages.

  The preparation of beverages by capsules containing beverage ingredients is known. Generally, a capsule is inserted into a beverage production device such as a coffee machine, liquid is supplied into the capsule, the liquid interacts with the beverage ingredients, and the beverage is extracted from the capsule under pressure or by gravity.

  The preparation of beverages by using centrifugal force is known. The principle is mainly that the beverage raw material is provided in the container of the capsule, the liquid is supplied into the container, the container is rotated at high speed, and the interaction between the liquid and the raw material is formed while forming a pressure gradient of the liquid in the container. The pressure gradually increases from the center of the container toward the outer periphery. As the liquid traverses the raw material, eg ground coffee, the beverage complex is extracted, resulting in a liquid extract that flows out of the perimeter of the container.

  The term “capsule” refers to any flexible, rigid or semi-rigid container that contains beverage ingredients. Other synonyms for capsule are “pod”, “pad”, “cartridge” or “bag”. The capsule may be disposable. The container can also be filled with raw materials by the user to form the capsule just before use.

  The term “raw material” is any suitable, such as ground coffee, water-soluble coffee, leaf tea, water-soluble tea, herbal tea, milk powder, cooking powder, baby food, other beverage nutritional ingredients, and any combination thereof Means beverage substance.

  The capsule system using centrifugal force is described in the following documents: European Patent Application Publication No. 2220539, International Patent Application Publication No. 2008/148604, International Patent Application Publication No. 2008148650, International Patent Application. It is described in Japanese Patent Publication No. 2008/148646, International Patent Application Publication No. 2008/148656, and International Patent Application Publication No. 2010/026045.

  It is known to use capsules in beverage brewing devices that use centrifugal force, in which case the closure wall of the capsule is removed or perforated so that liquid injection means and / or beverage extraction means can be inserted.

  However, in order to open the capsule, it is necessary to insert the capsule into a specific brewing device provided with piercing means. Therefore, the size and position of the opening is essentially determined by the form of the punching means of the brewing device. Therefore, the size and position of the opening cannot be changed to adapt the flow conditions to the desired type of beverage.

  Also, such means may become dull over time, so that the opening is not very effective or a greater force is required on the device to perform the drilling.

  The present invention aims to improve the principle by facilitating the opening of the capsule and giving more freedom to the opening of the capsule.

  Also, adapt the aperture to the type of capsule (eg, capsule volume) and / or beverage ingredients (eg, various coffee blends or teas) and / or beverage preparation type (eg, Listerotto, Espresso, Lungo, Americano, etc.) It may also be needed. In particular, it may also be useful to use the capsule in a brewing device with piercing means and in a device that does not have such piercing means but can still open the capsule properly. For example, it may be useful to have a capsule that can be manually drilled prior to insertion.

  The present invention provides a solution to the above objectives and possible further advantages. The capsule of the present invention, in particular, supplies liquid into the capsule and rotates the capsule along the central axis (I) to create a centrifugal force acting on the liquid across the capsule, thereby producing such centrifugal force. The beverage is designed to be prepared in a centrifugal brewing device by pushing the beverage out of the capsule by force, the capsule being closed by a body comprising a containment wall and a closure wall formed with the containment wall (I ) Main opening, a compartment for containing beverage ingredients, and a flange that bounds the outer periphery of the opening. The capsule also comprises a piercing wall disposed at a position close to the closing wall, the piercing wall perforating means for piercing the closing wall when pressure is applied to the closing wall and / or the piercing wall. Is provided.

  The capsule can be configured to be deformed at least in part by mechanical pressure, such as pressure exerted by a beverage brewing device or manually, such deformation being relative to the closure wall and the perforated wall. Cause serious engagement. Accordingly, the closure wall and / or perforation wall may be configured to be deformed by external mechanical pressure to perforate one or more beverage outlets of the closure wall. The capsule may also be configured to be deformed for such perforations by increasing the internal pressure of fluid and / or liquid within the capsule.

  In a first possible form, a closing wall is arranged between the perforated wall and the beverage ingredients. In this configuration, the perforation wall may be made deformable inward to perforate the closure wall. In particular, the perforated wall is at least partially convex outward before being deformed.

  In a second possible form, the perforated wall is arranged between the beverage raw material and the closed wall in order to separate the compartment from the closed wall. For example, the perforated walls can be arranged in parallel or inwardly convex to maintain a certain distance from the outer closure wall prior to drilling.

  The perforating means is preferably arranged at a position closer to the outer peripheral flange of the main body than the central axis (I). These piercing means in particular form a means for piercing the beverage outlet through the closure wall, such outlets allowing the delivery of the beverage from the capsule when a centrifugal force is applied to the capsule. To be arranged. The perforating means is preferably arranged in a region spaced from the flange by a distance of 0.5-12 mm, most preferably 1-8 mm. Such a distance allows the resulting outlet to provide a liquid flow path through all the raw material mass during centrifugation.

  These piercing means are preferably formed by a plurality of undulating (piercing) elements projecting from the piercing wall in the direction of the closing wall. The piercing element is axially above the compartment but on the outer circumference with respect to the central axis to pierce the beverage outlet in the closed wall in a region that promotes both upward and outward flow of the beverage in the compartment. It is preferable that they are arranged offset. These piercing elements are also preferably arranged along at least one circular path. These piercing elements can be evenly arranged along the path to provide a plurality of evenly arranged outlets in the outlet wall. Preferably at least three elements are provided, preferably at least four elements. Most preferably, the number of piercing elements is 5-30. The drilling means can be formed from a needle, blade, or cone or pyramid.

  The perforated wall also comprises a beverage outlet on the outer periphery of the perforated wall, the outlet being arranged above the compartment, and the compartment during the perforation of the closed wall to release the beverage through the perforated wall Communicate with. In one form, a piercing outlet is provided through the piercing means. The piercing outlet can also be arranged at or around the base of the piercing means.

  These features make the distribution of the liquid raw material mass within the capsule more uniform and avoid liquid shortcuts through the raw material mass, thereby improving raw material brewing, eg, coffee extraction.

  In a possible form, the further piercing element is also configured to form a central opening through the capsule. The piercing element is preferably further configured to provide a liquid inlet for insertion of a liquid injector and / or for supplying liquid into the capsule compartment. The perforating means for forming the beverage outlet and the further perforating means for forming the liquid inlet are preferably present on the same perforated wall. As a result, a perforation of the beverage outlet and the liquid inlet is provided in the same closed wall.

  Alternatively, a piercing element or undulating element in a further piercing means is present in the body of the capsule, for example in the bottom wall or side wall of the body, for piercing a second closing wall different from the first closing wall Can do. For example, the second closure wall can be disposed on the opposite side of the first closure wall.

  Generally, at least one of the undulating piercing elements comprises a through hole that traverses the piercing wall. In a possible form, each piercing element comprises a through hole that traverses the piercing wall.

  Preferably, at least one closed wall is formed from an airtight membrane. More preferably, a closed wall is used to ensure that there is no significant gas movement between the capsule compartment and the external environment that affects the freshness of these raw materials prior to use of the capsule (ie perforation). And the capsule body are airtight. More preferably, the compartment further contains an inert gas such as nitrogen and / or carbon dioxide and does not contain or contain a residual amount of oxygen.

  One or more hermetic membranes are formed from aluminum and / or a polymer.

  The capsule may further comprise a filter for filtering the beverage. The filter is preferably a separate element from the perforated wall. The filter preferably extends above the compartment in the transverse direction (ie substantially perpendicular to the axis I). The filter may be located, for example, adjacent to the perforated wall. The filter may be outside or inside the wall. The filter is preferably formed from a material that resists or deforms under puncturing forces, such as a flexible and / or elastic fabric (woven or non-woven) or filter paper.

  Protrusions and / or channels can be provided on the flange, either directly with respect to the flange or in the part of the flange of the closure wall and / or perforated wall connected to the flange of the body. The depth of the protrusion and / or channel is preferably 0.02 to 0.5 mm, more preferably 0.05 to 0.3 mm.

  The body of the capsule and the perforated wall are formed from aluminum and / or a polymer such as PP, PE, PA, PET, PLA, a biodegradable polymer such as a starch-based material or a polysaccharide, and combinations thereof. can do.

  The closure wall is a thin film of aluminum or polymer, such as PE, PET, PP, and combinations thereof, or metallized biodegradable polymer foil, such as polyhydroxybutyrate-metal-cellophane It is preferable that The membrane may have a thickness of 10 to 300 microns, more preferably 20 to 150 microns.

  In one form, the piercing means and the closure wall provide a filtering effect, for example, in a limited gap between the edge of the pierced orifice and the surface of the piercing means, so as to provide a filtering effect through the pierced orifice. Designed to. For this reason, the piercing means is preferably formed as a plurality of ridges or pyramids, and the closure wall is an aluminum foil with a thickness of 20-120 microns or a PP with a thickness of 10-60 microns. Alternatively, a polymer foil such as PE, or a laminate of aluminum and polymer (PE or PP) or a laminate of aluminum and filter paper having a thickness of 20 to 120 microns as a whole is selected. In this case, no further or separate filter layer is necessary.

  The invention also relates to the use of the aforementioned capsules in a centrifugal brewing device for preparing beverages.

The invention further relates to a method for preparing a beverage in a centrifugal brewing device by use of a capsule as described above, said method comprising:
Supplying a liquid into the compartment of the capsule;
Rotating the capsule along the central axis (I) of the capsule to create a centrifugal force acting on the liquid across the capsule, thereby pushing the beverage out of the capsule by such centrifugal force, traversing Piercing the closure wall of the capsule by applying pressure against the closure wall and / or the piercing wall, wherein such pressure is effective to pierce the closure wall by said piercing means .

  In the method of the invention, the pressure is machined by the part of the device that moves relative to the perforated or closed wall and engages the wall before or during insertion of the capsule into the device. In addition, the part can also be rotated to rotate with the capsule while the centrifugal force is applied.

  The invention is generally defined by the appended claims.

  Additional features of the present invention will become apparent in the detailed description of the figures that follows.

It is sectional drawing of the capsule of this invention which follows the AA line of FIG. It is a top view of the capsule of the present invention concerning the 1st form. FIG. 3 is a detailed view of the capsule of FIGS. 1 and 2. Fig. 4 shows the capsule of Figs. 1-3 in a centrifugal beverage brewing apparatus. It is sectional drawing of the capsule of this invention which concerns on a 2nd form. FIG. 6 is a detailed view of the capsule of FIG. 7 shows the capsule of FIGS. 5-6 in a centrifugal beverage brewing apparatus. It is sectional drawing of the capsule of this invention which concerns on a 3rd form.

  A first form of capsule is shown in FIGS. The capsule 1A according to the first embodiment includes a main body 2 having a storage wall, that is, a bottom wall 3 and a side wall 4. The body can be substantially cup-shaped. An outer peripheral flange 5 extends outward from the top of the side wall 4. An opening 6 is defined by the inner edge of the flange. Such an opening may be circular. However, the cross section of the opening is not necessarily limited to a circle, and may be an ellipse or a polygon depending on the shape of the storage wall. The flange thus forms an annular boundary surrounding the opening. Thus, the body forms a compartment 7 having a central axis “I” for receiving a beverage ingredient such as a fixed amount of ground coffee. The compartment 7 is closed by a closing wall 8 that may be sealed against the flange 5. Accordingly, the compartment 7 is defined by the storage walls 3 and 4 and the closing wall 8.

  A perforated wall 9 is also provided in the vicinity of the closing wall 8. In particular, the perforated wall 9 covers the closing wall 8 and is sealed to the flange 5 in a state where it overlaps with the sealing portion of the closing wall.

  The perforated wall 9 comprises perforating means such as a series of undulating elements 10, 11, 12, 13, 15. These elements may take various shapes such as spikes, blades, needles, pyramids. These elements are preferably arranged closer to the flange than to the central axis “I”. More preferably, these elements are located within a first length portion starting from the edge of the flange and indicating the first 1/3, most preferably the first 1/4 of the radius “R” of the opening. Is done. The outer peripheral position of the piercing elements 10-15 allows the release of the beverage or liquid extracted by centrifugal action, i.e. extracted when the capsule is driven at high speed about its central axis "I". It is important to provide a beverage outlet to the closing wall 8.

  The piercing elements 10-15 are preferably arranged along a circular path. However, other arrangements of these elements can be envisaged. The number of elements may vary from 3 to 50. A preferred number is 4-20. Too many elements can result in excessive piercing forces, whereas too few elements can cause inconsistent liquid distribution within the raw material and can cause mass loss in the capsule during rotation. This can lead to equilibrium, which can result in device vibration and noise.

In general, the cross section of the perforating element is preferably less, in particular 0.1 to 5 mm ^2, more preferably 0.5 to 2 mm ^2. Here, the cross-section is larger than the cross-section in the transverse plane of the element that can provide an opening in the closure wall. The axial length of the piercing element can be 2.5-15 mm, more preferably 3-8 mm. The piercing means may comprise piercing elements of different lengths in order to reduce the piercing force involved in the closure wall, especially when the number of elements is large (eg more than 10). For example, two sets of piercing elements of two different lengths can be used.

  The perforated wall is arranged at a certain distance with respect to the closed wall allowing a projection of the elements 10-15 in the narrow space 16. The perforating means is preferably arranged in a region spaced from the edge of the flange 5 by a distance of 0.5-12 mm, most preferably 1-8 mm. The perforation of the closed wall is here managed by applying mechanical pressure to the perforated wall to deform the perforated wall in the direction of the closed wall. The perforated wall is formed as a convex member having a central raised region 17, a lower flange region 18, and a transition region 19 that gradually increases in height and connects the first two regions 17,18 together. The transition region 19 may be formed with a thickness that is less than the thickness of the two other regions 18, 21. The transition region 19 may also be formed as a concertina or bellows to promote the deformation of the perforated wall in the direction of the closing wall.

  The perforated wall is provided with a through hole 20 for drawing the beverage from the capsule. Such holes may be provided through each or only part of the piercing elements 10-15, in which case the piercing elements are formed like hollow needles. These holes can also be placed close together, but they can also be removed from the cross section of the piercing element. The number of holes can be less, equal or greater than the number of piercing elements. The cross-section of the opening can be smaller than the average particle size of the raw material, for example ground coffee, thereby forming a perforated wall built-in filter. The cross section of the hole may be larger than the average particle size.

  A separate filter 21 may be provided to ensure beverage filtration. As shown in FIG. 3, the filter 21 may be disposed at a different position, for example, at a position outside the perforated wall adjacent to the perforated wall. In different possible forms, the filter is arranged in the compartment 7 or in the space 16 between the closed wall and the perforated wall. The filter may be formed from paper or woven or non-woven (natural and / or synthetic) or combinations thereof.

  The capsule may further comprise a beverage flow guide structure such as a radial channel 23 and / or a protrusion 22 in its flange. Such a beverage flow guide structure can be provided on the outer surface of the perforated wall. The beverage flow guiding structure can be formed on the flange between the closing wall 8 and the perforated wall 9 or on the flange between the closing wall 8 and the main body 2 or on the lower surface of the flange 5 of the main body. In general, the channels and / or protrusions are shallow in depth (axial dimension) to ensure a sufficiently small flow restriction of the beverage at the flange. Preferably, the depth is 0.02 to 0.5 mm, more preferably 0.05 to 0.3 mm. The dimensions of the channels and / or protrusions can be designed to create a pressure gradient within the capsule. In such cases, the pressure loss through the open area provided by the channel and / or protrusion is less than the pressure loss provided by the outlet 20 and the filter.

  Here, the action of the capsule in the centrifugal brewing apparatus will be described with reference to FIG. The capsule is inserted into the device 30 and in particular into a rotatably mounted capsule holder 31 which is shaped and dimensioned to properly reference the body of the capsule. A liquid interfacing member 32 is engaged with the perforated wall 9 of the capsule so as to deform the wall 9 inwardly. As a result, the closure wall becomes perforated by the perforating elements 10-15 at a number of peripheral positions 24. At the same time, the central inlet is pierced by a central injector 33 that penetrates both the piercing wall and the closure wall. The perforated wall may be formed from a relatively soft heat and / or liquid softening material that can be in fluid tight contact with the injector 33.

  Both the brewing unit formed by the capsule holder 31 and the liquid mediating member 32 fix and hold the capsule. In particular, the outer periphery fastening portion 34 of the liquid mediating member 32 is engaged with the flange of the capsule in a fixed manner or a spring biasing manner. The flange of the capsule becomes clamped between such a clamping part and the support part 35 of the capsule holder. Because the protrusions and / or channels are present in the flange, a gap can be maintained that allows the centrifugally applied beverage to be released through the clamped flange.

  In order to perform beverage extraction, the brewing unit is driven at a high speed (for example, between 500 and 1000 rpm) by the rotary motor 51 and liquid is supplied into the capsule through the injector 33. Such liquid may be warm water that comes from the reservoir 36 by gravity or a pump (not shown) and circulates in a liquid heater 37 (eg, a thermoblock, cartridge heater, or boiler). When the brewing unit is rotated, a mass of beverage raw material is agglomerated on the inner periphery of the containment wall, and the liquid interacts with the raw material across the resulting agglomerate, thereby allowing beverage or liquid extraction Things are formed. Such beverage reaches the holes 20 provided in the perforated walls, passes through these holes 20 and is projected in a centrifugal flow “F” through the channel 23 and hits the impingement wall of the collector 38. Thereafter, the beverage is collected via the beverage duct 39.

  5 and 6 show a second possible form of the capsule of the invention.

  In this capsule, the closing wall 8 is connected, for example in an airtight manner, to the flange 5 of the body 2 of the capsule in order to close the capsule. The perforated wall 9 is provided between the closing wall 8 and the cavity for the raw material. Such a wall 9 may be formed, for example, from an insert that is sealed and / or pressed into the cavity of the body. The piercing wall is provided with piercing elements 40, 41 or undulating elements. These elements are directed towards the closing wall 8 in the interstitial space 16 that exists between the two walls. In the perforated wall, for example, a through hole 20 provided through the perforating element is provided. The filter 21 is provided so as to cover the through hole. The filter may be disposed between the perforated wall and the raw material. A filter may be disposed across the gap space 16. In a manner similar to the previous embodiment, the capsule flange can be provided with protrusions 22 and / or channels to define a gap for the beverage to be subjected to centrifugal force. Such protrusions 22 and / or channels may be formed on the surface of the closure wall 8 or on the surface of the flange 5 of the body. When on the surface of the flange, this structure preferably projects upward by simply deforming or traversing the closure wall 8 with the flange. For example, the wall 8 may be aluminum, an aluminum-plastic laminate, or a thin flexible foil such as plastic.

  In FIG. 7, the capsule 1B which concerns on a 2nd form is shown in the state inserted in the brewing unit of the beverage brewing apparatus. The closing wall 8 is pierced against the piercing elements 40 and 41 of the inner wall 9 by the action of the liquid mediating member 32 that engages and deforms the closing wall 8. The closing wall 8 is deformed inward until it reaches the base of the protruding element. The liquid extract to which the centrifugal force is applied escapes from the brewing unit between the closed wall and the liquid mediating member, and passes through the channel 23 provided in the capsule flange.

  FIG. 8 shows a third embodiment in which further piercing means 50 are present in the piercing wall in order to provide a central inlet opening in the closing wall 8. Thus, the inlet opening is provided by the relative deformation of the perforated wall and / or the closed wall. The piercing means 50 may comprise a tubular part into which the injector of the device can be at least partially engaged. For example, the injector and tubular portion can form a fluid tight engagement by a close fit of the size and shape of the injector and tubular portion.

  In a possible variation (not shown), the piercing means and the closure wall are formed to filter the pierced orifice. A filtering effect is obtained between the edge of the perforated orifice of the closed wall and the outer surface of the perforating means. Thus, the drilling means may be formed as a plurality of ridges and / or a truncated pyramid. The closure wall is preferably a wall that closely fits with the piercing means so as not to form an excessively large orifice that results in the release of solids out of the capsule. In particular, the closed wall is made of aluminum foil with a thickness of 20 to 120 microns, or a polymer foil such as PP or PE with a thickness of 10 to 60 microns, or aluminum with a total thickness of 20 to 120 microns. It is selected from a laminate of polymer (PE or PP) or a laminate of aluminum and filter paper.

  It should be noted that the internal pressure of the liquid or gas in the capsule caused by centrifugal force is used to cause relative deformation of the perforated wall and / or the closed wall, thereby resulting in the perforation of the closed wall, etc. Other possible variations of the capsule are possible. In other variations, the pressure can be obtained by forcing a gas, such as air, under pressure toward the closed and / or perforated walls.
